To reduce the projection effect, we use the GCS model to get the real kinematic properties of the CME. The GCS model is developed to represent the FR structure of CMEs ([1]}; [2]}). It involves three geometric parameters: `h', the height of the leading edge, `\(\kappa \) ', the aspect ratio, and `\(\delta \) ', the half edge-on angular width, and three positioning parameters: `\(\theta \) ', `\(\phi \) ', and `\(\gamma \) ', the Stonyhurst latitude and longitude of the source region, and the tilt angle of the source region neutral line respectively. The GCS model is usually used to study morphology, position, and kinematics of a CME based on the best fitting result of a CME transient recorded in white-light images. The ice-cream cone model is another model of CMEs, which composed of a ball that we call the ice-cream ball and circular cone tangent to the ball with a conic node on the solar surface ([3]}). The GCS model becomes equivalent to the ice-cream cone model when its parameter \(\delta \) , equals 0 ([2]}). For our case study, we use the ice-cream cone model which is a simplified form of the GCS model and estimated the three-dimensional height and direction of the CME with LASCO C2, C3 and STEREO–B COR2 images. The best-fitted GCS model is displayed in Figure REF . The corrected CME speed from the GCS model comes out to be 450 km s\(^{-1}\) .
